Well, I'm surprised nobody suggested that the error message might be in tty1. Anyway, I managed to see that the error screen I got had tty1 written somewhere on it. So Ctrl+Alt+F1. Here's what it said (my computer name is "home-ubuntu" and this message may not be exact since I copied it on a piece of paper)
home-ubuntu login [ 123.468049] [drm: i810_wait_ring] *ERROR* space: 65520 wanted 65528 [ 123.468124][drm: i810_wait_ring] *ERROR* lockup I hope this helps in debugging... Do let me know if I need to extract some other data also. -- Ubuntu sometimes logs me out before login process is completed https://bugs.launchpad.net/bugs/500810 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gdm in ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
